- Metric Type Metric
- Metric Level Product/Service, Organization
- IRIS Metric Citation IRIS, 2021. Length of Coastline Restored (PI2538). v5.2.
Footnote
Organizations should footnote all assumptions used, as well as relevant ecological restoration activities undertaken during the reporting period.
Usage Guidance
-
This metric is intended to capture the entire length of coastline the organization is working to restore during the reporting period, not just any additional length of coastline that began restoration during the reporting period.
-
Climate change raises sea levels and intensifies storms, and coast erosion and land loss are a consequence. Restoring reefs, mangroves, and other stabilizing and wave-mitigating infrastructure can help create climate-resilient coasts. Protecting aquatic ecosystems near coastlines also counters the biodiversity decline threatened by the degrading effects of land use changes, pollutants, and invasive species.

Organizations can refer to the glossary for additional information on ecological restoration.
